Zcash's Zakura Node Aims to Revolutionize Private Transactions

Zcash, a leading cryptocurrency focused on private transactions, has taken a significant step towards achieving Visa-scale processing with its new full node software, Zakura. Released this week, Zakura is designed to handle tens of thousands of transactions per second while maintaining robust privacy guarantees. This ambitious goal is driven by the vision of supporting the world's payments, with the team setting its floor at 50,000 transactions per second, a figure that currently only global payment giants like Visa and Mastercard can achieve.

Zcash's Zakura node is a crucial step towards achieving a private and secure payment system that can support the world's transactions, but the real challenge lies in its scalability and efficiency.

Zakura is built on top of the existing Zebra node software, but with several key improvements that enable it to process high volumes of transactions efficiently. The software includes a pruning feature that allows nodes to delete old blockchain data, significantly reducing disk usage and enabling faster startup times. In fact, the team claims that Zakura can start up in under two minutes, a staggering 680 times faster than the original Zcash client.

The real challenge, however, lies in the development of recursive proofs, a feature that will enable nodes to verify thousands of transactions with a single proof, greatly reducing the amount of data that needs to be checked. This is where Project Tachyon, led by Sean Bowe, comes in, working on a solution that will make it possible for Zcash to reach its target of Visa-scale processing. With Zakura, Zcash is taking a significant step towards achieving its vision of a private and secure payment system that can support the world's transactions.
